I noticed on here many have depression. Please, those of you who have depression or any other mental illness, PLEASE PLEASE go to a regular doctor or neurologist and get checked out. depression, bipolar, schizophrenia, alzheimer, many of these "mental" illnesses they are finding out are caused by PHYSICAL DISEASES. some disease affect our heart, some our stomach, some our brain. when it affect the brain, it could cause symptoms that resemble mental illness. many people are misdiagnosed as having a mental disorder and years later find out it is a neurological or infectious disease, and get cured. sometimes i wonder if mental illness even exists. maybe all mental illness are caused by a disease and some are just caused by a disease they havent discovered yet.
